Round column mill CNC conversion restoration Part 1, Jet, Grizzly, rong fu, harbor freight, Maxnc

This mill is sold under many names like Jet 350020, Grizzly G0705, rong fu, central machinery, etc...The closed loop board was taken off a maxNC and uses high quality U made pacific scientific steppers. The spindle is controlled by a solid state relay. The conversion was done about 15-20 years ago. Interesting is mach3 these has a configuration for this and I got it working. Look at the similarities below.
